Focus on LNB

[satwyn]

Sorry dear, there is not much help on that page




Your all points are valid, In my issue I am only concentrating on KU-band LNB, 2nd, I just want to know, Can I use LNBF, like Inverto ultra Black on my Prime focus Dish ?

yes if they come in c120 to bolt onto a feed but you could also use a lnbf on your dish if you can mount if properly to the dish

Now later I try to attach a pic of my LNB and also feed I am trying

as previous pics , i really dont think you can get fred in the shed to make you a feedhorn to be any good.

you was advised to try and get a invacom universal( if i recall) then bolt up youre black ultra.

i dont think you are going to get a matched feedhorn for that dish so you are going to have to make good with whats available.

then work out (from the site i sent you) the focal point , and that will be the same if you use a feedhorn or just bolt up the lnbf.

then fine tune from there.

I have done some calculations

Dish size: 350 cm
Dish depth: 53 cm
Focal point of dish: 144.45 cm
F/D ratio: 0.41

The Invacom ADF-120 will manage up to F/D 0.43

I hope my calculations are correct...
